MG3 Hybrid+ 採用 Mild-Hybrid 輕混能系統，由一副 1.5 公升自然吸氣引擎配上 1.83 kWh 鋰電池同電摩打組成。呢套系統可以喺起步同加速時提供額外動力輔助，同時喺減速時回收能量，從而降低油耗，但唔可以純電行駛。
The MG3 Hybrid+ features a mild-hybrid system, comprising a 1.5-litre naturally aspirated engine paired with a 1.83 kWh lithium battery and an electric motor. This system provides additional power assistance during start-off and acceleration while recovering energy during deceleration, reducing fuel consumption without enabling pure electric driving.
